Re Addons, think we already had a discussion on it :

Well, tried to anyway.
Seeing my addon menu getting a bit populated now.
Personally I like / commands, but I can certainly understand users wanting to use the GUI as the number of options in one of my addons has grown quite a lot. But I would rather just have an option like
/jy setup that will then trigger XML Frames to configure that addon.
At least until we can get our own "Sub-config" setup, a bit like how Ace3 (I think it was) had all the addon with options in its own little GUI.
On Libraries, been thinking about making one so I grabbed LibStub to get an idea on how to go ahead.
Hopefully will figure it out.
